Cool Plasma Turbulence Visualizations

These first two visualizations of turbulence in a tokamak are from simulations by GYRO, a continuum/Eulerian 5-D gyrokinetic turbulence code, written by Jeff Candy and Ron Waltz (General Atomics). More GYRO movies.

Plasma Turbulence Movie of 3-D cutaway view of a shaped tokamak simulation, including beam-driven sheared flows. Note the simulation domain is not a whole torus, but of a hollow annulus.

Plasma Turbulence Movie of closeup of poloidal cross-section of a tokamak. Illustrates the nonlinear generation of zonal flows.

Visualizations of turbulence simulations by GS2, a continuum/Eulerian 5-D gyrokinetic turbulence code, written by Bill Dorland and Mike Kotschenreuther:

Plasma Turbulence Turbulence in a low aspect-ratio ST configuration. This also illustrates the alternative (and equivalent) flux-tube and wedge-annulus representations.

Plasma Turbulence Turbulence in a normal aspect-ratio tokamak configuration.
